Is it safe in the car when it thunders?

It is safe to stay in the car when it thunders for the following reasons:

Because the metal shell of the car is an equipotential surface, the potential of the people in the car is roughly equal to that in the car, and there will be no current flowing to the people in the car when lightning occurs. So it's safe to kill in the car when it thunders.

In fact, the principle of lightning protection is equipotential bonding, which is to connect metal objects with wires or other metal objects. When lightning high voltage is generated, the potentials of metal objects are almost equal, so there is no potential difference and no current passes through.

Lightning protection awareness:

Do not handle flammable materials in open containers. Leave the water and the boat. If you are traveling, stay in your car, which is usually a good lightning protection facility. When there is no shelter, you should avoid the tallest object in the area. If there are only isolated trees nearby, your best protection is to squat in the open air, and the distance from the isolated tree is twice its height.
